Patent GB-161682-A (GB)
Abstract: 161,682. Boardman, W. Jan. 14, 1920. Money-delivering apparatus.-In apparatus for cashing Treasury notes &c. comprising a vertical magazine containing superposed cash trays, a drawer at the base of the magazine for withdrawing one tray at a time, means for locking the drawer, an opening for the note and internal . mechanism for drawing in the note and subsequently releasing the cash tray drawer, the internal mechanism is normally locked by a pawl and a tumbler in the note opening is raised by an inserted note and releases the pawl. In the form shown in Fig. 1, a note inserted in the slot H raises a tumbler R and this acts through an arm R', lever 0 and pin 0<2> to raise a pawl P from locking engagement with a cam M carried by a shaft K; the shaft K is then rotated and causes a rubber-faced wheel L to carry the note to a receptacle G, while simultaneously the cam M acts through pawl P, link E<1> and a lost motion connection to disengage a catch E from the drawer D whereupon an arm N on the shaft K acts through bell-crank levers T, S to open the drawer which carries with it the lowest cash tray C. A catch E<2> prevents total withdrawal of the drawer and pawl and ratchet mechanism K<2> prevents reverse rotation of the shaft K. In the form shown in Fig. 2, a rocking shaft K is employed; insertion of a note releases the shaft which is then rocked by means of a lever F whereupon a pad W<1> carries the note to its receptacle and coacting arms V, U<3> move a spring-controlled slide U which first releases catches E, E<2> and then opens the drawer D. The apparatus is duplicated to change notes of different denomination and size, the opening for the smaller note being too small to receive the larger note and the tumbler in the opening for the larger note being out of reach of a smaller note.

Title: Process for the production of hardenable condensation products
IPC: C08L61/10
Filed: 1955-06-06
Abstract: Epoxy resins soluble in the usual solvents for such resins, e.g. ketones and glycol monoethers, and suitable for casting or for electrical insulation, are produced by reacting an epihalogenhydrin in alkaline medium with a novolak which has been produced by reacting excess phenol with formaldehyde under acid conditions, separating the aqueous layer and distilling to remove excess phenol and render the resin anhydrous, excess phenol being added during the novolak-epichlorhydrin reaction; alternatively the novolak containing the original excess phenol and without dehydration may be reacted with the epichlorhydrin.  The additional phenol added may be phenol, cresol, xylenol, chlorphenol or their glycide ethers may be employed. The optimum formaldehyde/phenol ratio for the production of the novolak is 0.5, but for phenol homologues, e.g. p- or o-cresol the ratio may be somewhat higher.  The product may be mixed with fillers or dyestuffs and then hardened by addition of conventional hardening agents, e.g. amines-triethanolamine or piperidine, or polybasic acids or their anhydrides, e.g. phthalic and maleic acids, (1) 440 gs. novolak produced by reacting formaldehyde and phenol in molar ratio 0.5/1 and freeing the product of water and phenol by distillation is mixed with 170 gs. phenol dissolved in 2400 gs. 10 per cent NaOH solution and 556 gs. epichlorhydrin are added, the resulting exothermic reaction being maintained at 80 DEG  C. by cooling; the resin is dehydrated by decantation, distillation and purified by solution in acetone and filtering followed by distillation or reduced pressure.  In Examples (2)-(5), the novolak obtained in Example (1) is reacted with epichlorhydrin and (2) cresol, (3) xylenol, (4) glycide phenol ether, (7) chlorphenol.  In Examples (5) and (6) a cresol-formaldehyde novolak is reacted, (5) with phenol, and (6) with cresol.  Example (8), 1410 gs. phenol, 645 gs. 36 per cent formaldehyde and 14 gs. oxalic acid are boiled under reflux; the CH2O content of the aqueous layer is then 0.2-0.3 per cent 600 gs. NaOH dissolved in 6000 gs. water are added, the mixture is heated to 60 DEG  C. and 1390 gs. epichlorhydrin added; after decantation, washing and filtration, 1840 gs. resin are obtained.

Title: Process for the production of hydroxy benzaldehydes
IPC: C07C47/56
Filed: 1963-04-26
Abstract: A process for the production of ortho-, meta-, or para-hydroxy benzaldehydes comprises oxidizing the corresponding hydroxybenzyl alcohol in aqueous medium with oxygen in the presence of palladium catalyst.  The hydroxybenzyl alcohol may be substituted in the nucleus by halogen, alkyl or alkoxy radicals.  The aqueous medium is preferably made alkaline by sodium or potassium hydroxide and contains boric acid or a borate.  In an example carbon black containing 10% of palladium, orthohydroxybenzyl alcohol dissolved in potassium hydroxide to which is added boric acid are placed in a flask and oxygen at atmospheric pressure passed in until absorption of oxygen ceases.  The product is centrifuged to separate the catalyst and the filtrate, which contains salicylic aldehyde in the form of its sodium salt and sodium borate, is acidified and the liberated aldehyde is steam-distilled and separated from the water by decantation, and the aqueous layer is then extracted with diethyl ether and the ethereal extract is combined with the decanted organic layer dried and evaporated to give a product containing 98.1% of salicylic aldehyde.  Other examples are given.  Specification 774,696 is referred to.

Title: Improvements in or relating to apparatus for the recording or reproduction of sound films and the like

Abstract: 458,349. Sound-film and like speedcontrolling devices. AGA-BALTIC RADIO AKTIEBOLAG, Lidingo, near Stockholm. June 15, 1936, No. 16652. Convention date, June 13, 1935. [Class 40 (ii)] Apparatus for recording sound on or reproducing from films or the like, including a flywheel 5 and two tensioning members such as jockey rollers 3, 9 situated on each side of the flywheel and forming loops in the film, is characterized in that the tensioning members are connected to each other by an energy absorbing coupling, such as a dashpot 17 and links 18, 19, in such a manner that alterations in tension (increases or decreases) due to oscillations in one of the loops are accompanied by inverse alterations in tension (decreases or increases respectively) in the other loop. By this means, low frequency speed variations as the film passes over the roller 6, to which the flywheel is connected are damped out. High frequency variations are damped out by the action of the flywheel, the mass of which is great relatively to that of the other moving parts. For this reason, the rollers 3, 9 and the arms 11, 12 carrying them are preferably made of light metal. The arms, as well as the rollers 3, 9 and the guide rollers shown are mounted on ball bearings. The links 18, 19 are resilient, to assist the attenuation of high frequency oscillations. Instead of a dashpot, an eddy current brake, a frictional shock-absorber, or the like may be used. The invention is applicable not only to optical but also to magnetic and mechanical recording and reproducing apparatus.
